" 4 claims. (on '15e-17) This invention relates to blinds of the-so-called "Venetian type used for closing openings such as windows or the like. Y

The principal object of the inventionis to pro- '5 vide a Venetian blind, composed of a plurality of co-acting shutters, in which preselected groups of the shutters may be .moved independently of others of the shutters so that fractional por tions of the opening, in which the blind is mounted, may be closed while'the other portions of the the specific form thereof shown and described as various other embodiments thereof may be employed within the scope of the appended claims. 4 l

5 Referring to the drawing:

" Figure l' is a perspective view of a Venetian blind structure incorporating the improvements of my invention.

Figure 2 is a perspective diagrammatic view showing the arrangement of the control cords.

The greater part oi' Figure l illustrates a conventional Venetian blind structure comprising a support t which may bethe frame of a window, or a door, inthe opening of which the blind is mounted. Secured to the' upper portion of the frame, within the opening, by screws, or otherwise, is a header t provided at opposite endswith brackets t on which is supported for rotary movement about its longitudinal axis, a rocker bar l. Attached to opposite edges of the rocker bar,

in spaced relation, is a pair of fabric tapes 8'Y depending from the bar to form loops and provided at spaced intervals with connecting webs s upon which rest the shutters II. It will be seen that the spacing of the webs e, along the fabric loops, determines the spacing of the shutters. Secured in the lower end of each of the loops is a bar I 2 which acta as a weight to maintain the tapes t taut. @ne of the brackets 6 encloses ,-,Olsuitable gearing, not shown, which may be actuated by pull chains i3 to cause rotation of the rocker bar l and consequently cause the opposed tapes 8 of each loop to move in opposite directions thereby moving the shutters il into overlapped positions, similar to that in which the group of shutters in the lower portion of Figure 1 is? shown, to cover the window or door opening. Each of the shutters II and the rocker bar i are provided with alined apertures I4 through which pass cords I6 the lower end of each of which 5` is secured to the bar I2 and the upper portions thereof passing into the header 4 through apertures I'I and outwardly therefrom through apertures I8 located adjacent one side of the frame 3 and terminating together in a connector I9. l0 Itwill be seen that by pulling downwardly on the connector I9 the bar I2 will be moved toward the upper part of the frame thereby collapsing the blind and uncovering the greater part of the opening to permit passage of the maximum l5 amount of light therethrough. 'Ihe structure and the operation thus far described will be recognized as the conventional Venetian blind in which the shutters II may, by the pull chains I3, be moved, as a group, to pozo sitions wherein they are disposed edgewse and thereby provide the leastdegree of obstruction to light coming through the opening, or to positions wherein they are broadside to the light thereby covering the opening and permitting the 2-5 passage therethrough of a minimum of light. I have provided means whereby separate groups of the shutters. may be opened or closed independently of the other groups thereby permitting the covering or uncovering of as little or as great 30 a. portion -of the area of the opening as desired. Secured to the underside of the rocker bar 'I is a pair of spaced staples 2i, or their equivalent, which provide guides for control cords 22. The

' arrangement of the control cords may be more 35 readily understood by reference to Figure 2 of the drawing. It will be seen that each of the control cords is double,- the right hand set comprising the lead 22 which passes through the right hand staple 2i and downwardly therefrom 40 to connect with the forward edge of the shutterA ii, an' aperture 23V being provided in the shutter to facilitate the connection of the cord by means of the knot 2t. The othert lead 2670i the pair passes through the right hand staple 2i across 45 and through the left hand staple and downwardly to be joined with the forward edge of the shutter in the same manner as the lead *22 is connected. The left hand control cord comprises a lead Y 2l' which passes through the left hand staple 50 and downwardly to connect with the rear edge of the shutter, and a lead 28, which, after passing through the left hand staple crosses over and passes through the right hand staple and thence downwardly to be secured to the rear edge of 55
